Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication elements are laid out at vertices of a grid-like or triangular drawing on the surface of the sheet-like body, then local communication between adjacent elements is achieved, but signal transmission to distant elements suffers attenuation
Solution Approach 1:
The patent introduces relay communication elements that act as intermediaries to receive signals from transmitting elements and re-transmit them to destination elements. This mediator mechanism enables signals to hop through multiple intermediate nodes rather than attempting direct long-distance transmission, thereby maintaining signal strength and reducing attenuation effects.
Solution Approach 2:
The communication path is segmented into multiple hops through intermediate relay elements. Instead of treating communication as a direct point-to-point connection, the system divides the transmission path into sequential segments, each involving a transmitting element, one or more relay elements, and a destination element, with each segment maintaining reliable local communication.
2Productivity
If communication elements communicate only with neighboring elements using intensive transmission to neighborhood, then local communication efficiency is improved, but complex routing and management functions are required for distant communication
Solution Approach 1:
Communication elements autonomously determine their roles (transmitting, relay, or destination) based on embedded identification information and communication rules. Each element independently performs routing decisions and signal processing without requiring external control, enabling the network to self-organize and reduce management complexity while maintaining efficient local communication.
3Adaptability or versatility
If a sheet-like communication unit is designed with multiple layers and resistor sections, then information transmission capability is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple functional layers (conductive layers, insulating layers, resistor sections) into an integrated sheet-like structure where components are formed in overlapping or adjacent regions. Conductive patterns, resistors, and insulating layers are merged into a unified multi-layer construction that achieves complex transmission functionality while enabling batch manufacturing processes.
Solution Approach 2:
Different regions of the sheet-like body exhibit locally optimized properties: certain areas have high conductivity for signal transmission, other areas have resistive properties for signal conditioning, and specific regions have insulating characteristics for isolation. This spatial variation in material properties enables diverse communication functions within a single integrated structure.
